    Abstract: 自1955年起許多量測地表附近次級宇宙射線能譜的實驗在各地進行,而其中多數的實驗都是觀測μ+ 與μ- 的能譜,對於質子能譜以及天頂角分佈的觀測則較為缺乏。而此次我們的實驗透過解析度較佳的矽探測器以及塑膠閃爍體加上光電倍增管所製成的觸發探測器,觀測地表附近次級宇宙射線中質子的能譜,另外也透過可轉動式支架讓此次實驗可以觀測較大範圍天頂角的能譜,提供分析質子能譜與天頂角關係。實驗進行前我們對探測器架構做許多相關的模擬分析,包括誤判事件多寡、各角度接收度修正等,這些結果將可在作為日後量測資料的參考與校正。最後,整個探測器建構測試完成後,我們在實驗室內作初步的量測並將所得資料作分析,然後將分析結果與預測結果做比較,獲得初步的結論。 There are many experiments about partice spectrum of cosmic ray at sea level from 1995.Most of them observe Muon spectrum,and experiments about Proton spectrum are few.On the other hand,Observation of spectrum in differnt zenith angle is deficient.Our experiment is designed to observes Proton spectrum of differnt zenith angle in larger scale,and we hope get more data to study about proton spectrum at sea level.
